Last years the attention of scientists and technologists of many
countries is involved in ceramics - to a firm material of the inorganic
nature. This material has found such wide application that the end of
the twentieth century began to name an era of ceramics.

The high
mechanical durability remaining even at extreme temperatures, the big
corrosive fastness, high electrical insulation properties cause
uprising ceramics application in various areas of engineering and
manufacture.
Despite the modern scientific achievements in the field of medicine the
prospects of use of the newest materials is of special interest.

Materials traditionally used in implantology — metals, aren't
physiologic: they cooperate with tissues, as a result of transport
reactions are transferred to other parts of a body, changing immune
reactions of the person though are convenient in manufacturing and the
installation. Even the most inert of the metals titanium in a few
months after implantation is found in the lungs, liver, kidneys and
lymph nodes.
Ceramics as a material for implants for a long time involved
researchers, but rather fragile characteristics didn't allow their
effective application yet unique properties of stabilized zirconium
dioxide as material for implantation, until recently, haven't been
revealed.

Absolute inertness, firmness and biocompatibility of ceramics
of a dioxide of zirconium with an osteal tissue promotes its best
osteointegration that gives them conclusive advantage.
